CHARLES KING, OF GRAND RAPIDS, MICHIGAN.

CARPET-SWEEPER.

SPECIFICATION'forming part of Letters Patent No. 575,960, dated January26, 1897.

Application filed January 25, 1896. Serial No. 576,902. (No model.)

To ctZZ whom, it may concern:

Be it known that 1, CHARLES KING, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented new and useful Improvements in Carpet- Sweepers, of whichthe following is a specification.

My invention relates to improvements in the carpet-sweeper described andshown in my application, Serial No. 555,655, filed July 11, 1895, andits objects are to make improvements therein,as will be set forth in theclaims. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is a transverse verticalsection of the case on the line or wof Fig. 3, showing the relativepositions of the several operative parts. Fig. 2 is a perspective of myadjustable wheel-supports. Fig. 2' is a perspective of my stationarywheel-support. Fig. 3 is a longitudinal section of the case. Fig. 4. isa front elevation of the pan supporting and actuating mechanism with aportion of the case and the pan shown in outline. Fig, 5 is a sideelevation ofthe same with an end view of one of the pans. Fig. 6 is aplan, and Fig. 6' is an edge view, of the plates to which thebrush-shaft is pivoted. Fig. 7 is a perspective of the lever with whichthe pans are dumped. Fig. Sis a perspective of the pandumping mechanismdetached from the lever; and Fig. 9 is a perspective of the adjustingmechanism for the drive-wheel, shown as attached to a section of the endof the case and the wheel shown in outline beyond.

Similar letters refer to similar parts throughout the several views.

My appliance for supporting the pans E consists of the levers G, pivotedto the ends of the case A, as at 0, each with a short arm extendingupward to connect with the handle-bow H, as at c, and two lateral armsextending some distance each way from the pivot-point c and havingpivoted to the end of each a connecting-rod O, which extends thencedownward and is connected with the inner edge of the end of the adjacentpan by means of the short bearing c",passing through the end of thepanloosely, so that the pan is pivoted thereon. To hold the pan to aproper position, I pivot links 0 at one end to each of the bearings c"and the opposite ends to the case, as indicated in Fig. 1.

I support the outer edges of the pans E by means of the arms G Each isattached to the pans at one end bymeans of the hookg, passing throughthe end of the pan, (see Fig. 4.) and the other end is attached to thehub G, which hub passes through the end of the case (indicated by thedotted lines in Fig. 4:) and has attached to its outer end a lever G, bymeans of which it may be manipulated to dump the pan, as indicated bydotted lines to the rightof Fig. 1. The handle G may be secured to thesupport G by any suitable means, as the entrance of the fingers g intothe apertures g and riveting or otherwise. To theinner end of the hubG,I attach'a short 1ever F, which is actuated by the spring F (theopposite end of which is attached to the case) to throw and hold theouter edges of the pans to their normal position in the case, as in Fig.1.

For manipulating the levers O for throwing the inner ends of the pans upand down I form slots to through the ends of the case in position toallow the projections c on the ends of the handle-bow to pass throughand work from side to side alternately as the handle is drawn or pushedupon, so that the connection with the short vertical arm of the lever Gwill cause the lateral arms of the lever to raise and lower, and withthem, through the medium of the connecting-rods O, the inner ends of thepans, all of which motions are indicated by the dotted line upon theleft side of Fig. 1.

Mymeans for supporting the brush-shaft B consists of thin steel platesJ, having an aperture j, through which the projections c on the,

handle-bow H pass and a countersunk aperture j to receive the centers 19at each end of the brush-shaft. These plates are attached at one end tothe ends of the case in position to act as a guard for the projectionson the handle-bow, as above suggested, and the other ends projectdownward to position to receive the centers bin the brush-shaft and areheld in contact therewith by the spring of the guards K. With thisconstruction the brushroll may be readily inserted or removed by simplyspringing the guard and the plate sufliciently to admit of theconvenient manipulation, as indicated by dotted lines in Fig. 0. Theheads of these plates are made broad enough each side of the aperturejto completely cover the slot a in the ends of the case.

One pair of the wheels I of my sweeper are supported on the pins (1 onthe stationary supports D, which are solidly attached to the ends of thecase, as indicated in Fig. 1. The other pair of Wheels 1 are supportedupon similar pins at the lower ends of the leverD. These levers arepivoted (one at each end, as in Fig. 3) to the ends of the case, as atd, (see Fig. 1,) with the pins projecting through slots 61 in the endsof the case for the support of the Wheels outside of the case, and areheld in position by springs D These springs are securely attached at oneend to the ends of the case and flexibly attached at the other ends tothe upper ends of the levers D, as at (Z in Figs. 1 and 9.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

1. In combination with the case and dustpans of a carpet-sweeper, leverspivoted one to each side of the case, an arm projecting upwardly fromeach lever, the handle-bow of the sweeper connected at its ends withsaid arms through slots in the case, lateral arms projecting from eachside of the levers, each connected with the inner edge of the panadjacent to it, and spring-supports for the outer edges of the pans,substantially as shown and described.

2. The combination with the case and dustpans of a carpet-sweeper,levers pivoted one to each side of the case, an arm projecting upwardlyfrom each lever, the handle-bow of the sweeper connected at its endswith said arms through slots in the case, lateral arms projecting fromeach side of the levers, each connected with the inn er edge of the panadjacent to it, revoluble bearings passing through apertures in the endsof the case and levers attached to the outer ends thereof, arms eachpivoted at one end to the outer edges of the pans and secured at theother end, to one of said revoluble bearings, and arms on the inner endsof said revoluble bearings and springs attached thereto and to the caseand adapted to return the pans to their normal position, substantiallyas and for the purpose set forth.
